Increased iodine-123-iodoamphetamine uptake in hepatomas
In the current study, two cases of hepatoma are reported in which N-isopropyl-(I-123)-p-iodoamphetamine (IMP) liver scan demonstrated increased accumulation in the tumor corresponding to the areas enhanced on contrast enhanced CT (CE-CT). In contrast, there was no IMP accumulation in the necrotic area of the tumor in which no enhancement was found on CE-CT. Thus, IMP liver scan seems to have the potential to assess the viability of a hepatoma as well as to detect and localize it.
